DEVICE FOR 'STACKING LOOSE HAY OR STRAW.

SPEGIFICATION forming part of Letters Patent No. 664,546, dated December 25, 1900.

Application filed March 20, 1900. Serial No. 9,387. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT GRIsWoLD, a citizen of the United States, and a resident of Grover, in the county of Weld and State of Colorado, have invented a new and Improved Device for Stacking Loose Hay or Straw, of which the following is full, clear, and exact description.

My invention relates to portable machines adapted for unloading loose hay and straw and stacking the same and the purpose of the invention is to form a well-ventilated stack and also to provide a very simple and eco nomic construction4 of directing platform which when usedin connection with a hoistrope, guide-ropes, and a sling may be conveniently utilized to convey the hay in the form of a roll from a wagon to the ground where the stack is to be formed.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had tothe accompanying drawing, forming a part of this specification, in which is represented a perspective view of the improved structure, illustrating the manner in which the hay is rolled over the same.

The directing-platform A is preferably of slatted construction, and its top is inclined from the rear downward in direction of the front. The said structure usually consists of side pieces 10, cross-bars 11, uprights 12, and cross-braces 13, together with end braces 14, which extend from the bottom of the structure at the rear to the upper rear cross-bar, and preferably longitudinal boards or beams 15 are located in suitable numbers at the rear of the said platform,` The upper rear crossbar of the directing-platform A is designated as 11a and diers from the other cross-bars inasmuch as two are employed instead of but one, and a space 11b intervenes the opposing inner ends of the said bars. Diagonal beams 16 extend from the `bottom portion of the directing-platform into the central portion of the said space 11b, connected with bars 17, grouped quite close together at the central portion of the top of the directing-platform, extending practically from the front to the rear. A pulley 18 is mounted between the upper ends of the beams 16 and the rear ends of the bars 17, and the pulley is provided with a guard 19, which rests upon the bars 17, and the sides of the guard are inclined downward in direction of the side portions of the opening 11".

A rail 20 is horizontally located at the front lower portion 0f the directing-platform A, and this rail is usually supported by standards 21, adapted to engage with the ground, and side bars 22, which are secured to the side portions of the platform, and when a haywagon is brought close to the directng-plat form the rack of the wagon is adapted to extend over or upon the rail 20, so that a person may conveniently pass between the rail and the front of the directing-platform to attach guide and draw ropes to the sling or receptacle in which the hay is placed.

The directing-platform is mounted upon a base B, and this base preferably consists of a series of runners 23, suitably braced, and end sills 24, and the directing-platform at its bottom is fitted upon the base between the sills 24. A series of guide-ropes 25 extend from the rear of the directing-platform forward and downward and in front thereof, the guideropes 25 terminating in snaps 26 or their equivalents. Preferably the rear portion of the guide-ropes is'passed over the upper rear cross-bar 11EL of `the directing-plat4 form, the rear ends of the guide-ropes 25 being finally secured in any approved manner to said cross-bar lla, at the rear thereof.

In connection with the directing-platform a sling C is employed, and this sling preferably consists of a series of ropes 29,arranged in pairs, each rope being provided at one end with a ring 30, while at the other end of the sling the ropes 29,although shown as arranged in pairs by engagement with rings 31, are preferably each provided with an individual ring. At this end of the sling the ropes are usually of varying lengt-h, the central ropes being longer 0r extending beyond the outer ropes.

A h0istrope 28 is employed, and this hoist# rope is passed over the pulley 18 and is provided with a series of strands 32 at its forward end, the central strands being shown Vshorter than the outer strands, and each of these strands 32 is provided with a snap33, adapted for engagement with a ring 31 of the sling C. The hoist-rope 28 is carrie-d rearward and downward and over a pulley 34,

preferably attached to an inclined stake 36, suitably secured in the ground, and the rear end of the hoist-rope 28 is attached in any approved manner to a singletree or to a doubletree 375. The inclined post 36 is held in its inclined position in any approved manner, and a stay 38 is usually employed, which extends rearward from the upper portion of the post to an engagement with a pin 39, the latter being driven in the ground.

In operation thesling is placed upon the rack of a wagon and the hay is loaded thereon. When the wagon is brought alongside of the front of the directing-platform, the

'rack will engage with or will extend slightly e fver the front rail 20, enabling a person or persons to readily attach the forward ends of the guide-ropes 25 to the ends of the sling C' which are nearest the platform. The hoistrope is then carried over the load and its strands 32 are attached to the rings 31 of the sling. The hoist-rope 28 is now drawn rearward by means of a team, by a single horse,.

or by other means, and the hay will be removed from the rack of the wagon in the sling and will be carried in the shape of a roll up the front of the directing-platform.

and along the upper surface of the same. Should'the longer strands 32 of the hoist-rope reach the rear portion of the platform too soon, the shield 19 will direct the strands to each side of the shield and prevent them catching on the ends of the timbers, and when the roll of hay approaches dumping position it will cause the draw or hoist rope to disengage from the pulley 18, thus permitting a roll or bunch of material to be freely and cleanly dumped. The spaces 11b enable eight vor more strands to be used in the formation of the hoist or Vdraw and the sling, and these spaces aiford ample clearance for the outer strands of such parts and prevent them from binding on the rear portion of the platform. When the roll of hay reaches the rear end of the platform, it drops 'from the guide-ropes and likewise' from the hoist-rope, whereupon the sling is again carried to the rack of the wagon and the. guide-ropes are made to assume their normal position upon the platform. The hay is dumped upon a ventilating device D, which is adapted to extend from side to side of the central portion of the stack, and this device consists of end sections 40, intermedi-ate sections 43, side slats 42, and a top bar 41. Any number of these ventilating devices D are employed, and they are adapted to remain in the stack.

In addition to the Ventilating devices shaping devices E are employed yfor the side portions of the stack. These shaping devices con-sist of a series of uprights 44, having suitable cap-pieces 45,.upon which series of boards 46 rest on their longitudinal edges, the boards being connected by cross-bars 47 in such manner that spaces intervene them, and braces 48 are also preferably employed to connect the upri'ghts with the top portions of the shapingrdevices. After the stack has beenformed the braces 48 and the uprights 44 are removed, whereupon the series of connected boards 46 will drop to the ground, permitting the stack to sag at its bottom outer edges, and at the same time the bottom of the stack will be in a great measure ventilated at the sides.

Each Vsnap carried by a strand of the hoist or draw rope 28 is preferably made to engage with the rings 31 of two members of the sling, especially when many ropes are used in the formation of the sling, and each member of the sling may be engaged by a separate snap if necessary.

Having thus described my invention, -I claim as new and desire to secure by Letters Patent- Y 1. In adevice for stacking hay and the like, a directing-platform, a guide-pulley at the rear of the directing-platform, the platform having a space at each side of said pulley, guide-ropes attached to the platform at the rear and arranged to extend across the same and down to the front, a hoist-rope arranged to pass over the pulley, strands of varying lengths attached to the forward end of the hoist-rope, and a guide for the hoist-rope independent of the platform.

2. In a device for stacking hay and the like, a directing-platform having an inclined upper surface, a guide-pulley located at the central portion of the higher part of the platform, a space being provided at each side of the pulley, a guard for the pulley, sloping in direction of the said spaces, guide-ropes extending from the higher to the lower portion of the directing-platform,4 a hoist-rope arranged for engagement with the said pulley, means for exerting tension on the hoist,

rope and guiding the same independent of the guide-pulley, a sling, and means for connecting the sling with the hoist and guide ropes.

3. In adevice for stacking hay and the like, a directing-platform havin-g an inclined upper face, the inclination being from vthe rear in direction of the front', said plat-form likewise having a space provided at its upper rear portion, a guide-pulley located in said space, a guard for lthe pulley inclined indirc'ctio'n of the space, a hoist-rope arranged for engagement with the pulley, provided with strands of varying lengths, guide-ropes extending from the upper to the lower portion of the platform, anda sling having the members at one of its ends varying in length, which ends are adapted for connection with the strands of the hoist-rope, the other ends of said members being adapted for rattachment to the guide-ropes, as specified.'

In testimony whereof I have Signed my name to this specication in the presence of two subscribing witnesses.
